LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 244,621, dated July 19, 1881,,

Application filed June 10, 1881. (No model.) 9

To all whom it may concern:

Beit known that I, JOHN A. KLEIN, of J oanna Station, in the county ofBerks' and State of Pennsylvania, have invented certain new and useful Improvements in Hinges; and I do herebydeclare that the following is a full, clear, and exact description of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference bein ghadto the accompanyingdrawin gs, which form a part of this specification.

Figure 1 is a perspective view. Fig. 2 is a top plan. Fig. 3 is a horizontal sectional view. Fig. 4 is a view of the leaves separated, and Fig. 5 is a detail view of the latch.

, Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to hinges for window shutters and blinds, which said hinges are so constructed as to retain theshutters or blinds in an open position when so adjusted, a suitable spring-latch being employed for this pur-' The leaf 0 of the hinge is provided with a fflange, H, extending horizontally, as shown,

and provided with a notch, I, which,whenthe hinge is one-fourth open, will enable the leaf 0 to be lifted off the main leaf A, thus enabling the shutter orblind to be removed. When in any other position the leaves A and G are .inseparably connected.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. The construction is simple and inexpensive, and my improved hinge is more easily adjusted and operated than shutter-fasteningdevices of a more coinplicated construction.

'Havingthus described myinvention,1claim and desire to secure by Letters Patent of the United States-- The combination of theleaf A, having socket D, notched and longitudinally-slotted latch E,

spring G, and the leaf 0, having notched flange H, substantially as herein described, for the purpose shown and specified.

In testimony that I claim the foregoing as my ownI have hereto affixed my signature in presence of two witnesses.

JOHN A. KLEIN.
